Subject: s390x: add TR function for EXECUTE
X-Git-Tag: qemu-xen-4.2.0~39^2~1
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=8a0a9cf35bd1abc7a9a11f430a6b14e034f34ba0;p=qemu-upstream-4.2-testing.git

s390x: add TR function for EXECUTE

Newer gcc versions (or glibc?) also generate code that tries to EXECUTE
the TR opcode. Implement it so that we don't break valid guests.
